The embodiments described herein with reference to theaccompanying drawings are explanatory and illustrative, which are usedto generally understand the present disclosure. The embodiments shallnot be construed to limit the present disclosure.

FIG. 1 is a block diagram of a switch assembly according to anembodiment of the present disclosure. The switch assembly comprises awireless switch 100, a wireless receiver 200, a controller 300 and acontrolled component 400. The wireless switch 100 comprises a controlswitch 110, a wireless transmitter 120 and a first identification card130. The wireless transmitter 120 is connected with the control switch110 for transmitting a corresponding control signal according to aninstruction from the control switch 110. The first identification card130 is pluggably mounted in the wireless switch 110 and connected withthe wireless transmitter 120. The wireless receiver 200 is connectedwith the controller 300 of the controlled component 400, communicateswith the wireless switch 100 via a radiofrequency signal or an opticalsignal, and has a second identification card 210 pluggably mounted inthe wireless receiver 200. Corresponding identity codes are set in thefirst identification card 130 and the second identification card 210respectively, the wireless receiver 200 first determines whether anidentity code carried by the control signal matches an identity code setin the second identification card 210 after receiving the control signalfrom the wireless switch 100, and only when the identity code carried bythe control signal matches the identity code set in the secondidentification card 210, the wireless receiver 200 feeds the controlsignal to the controller 300 and the controller 300 controls thecontrolled component 400 according to the control signal.

In one embodiment, corresponding identity codes are set in the firstidentification card 130 and the second identification card 210respectively, only when the identity code set in the firstidentification card 130 matches the identity code set in the secondidentification card 210, the wireless switch 100 and the wirelessreceiver 200 may be matched, that is, functions of controlling and beingcontrolled may be achieved. The wireless transmitter 120 is connectedwith the control switch 110 for transmitting a corresponding controlsignal according to an instruction from the control switch 110. In someembodiments, the wireless receiver 200 is connected with the controller300 of the controlled component 400, and communicates with the wirelesstransmitter 120 via a radiofrequency signal or an optical signal. In oneembodiment, the wireless receiver 200 communicates with the wirelesstransmitter 120 via a radiofrequency signal. The wireless receiver 200first determines whether an identity code carried by the control signalmatches an identity code set in the second identification card 210 afterreceiving the control signal from the wireless transmitter 120, and onlywhen the identity code carried by the control signal matches theidentity code set in the second identification card 210, the wirelessreceiver 200 feeds the control signal to the controller 300 and thecontroller 300 controls the controlled component 400 according to thecontrol signal. The identity code may be an identification codeconstituted by a multi-bit code, for example, 128-bit. Therefore, if thefirst and second identification cards 130, 210 with very simplefunctions are customized, a cost is very low, and the first and secondidentification cards 130, 210 may be used on a large scale. In oneembodiment, the first identification card 130 and the secondidentification card 210 are both programmable. In this way, even for avery complex application scenario, identification codes in theidentification cards may be field programmed according to a requiredtopological structure, thus facilitating user's flexible configuration

It should be noted that embodiments of the present disclosure may notonly apply to wireless switch field, but also apply to infrared remotecontrol field or short-distance wireless transmission field.

Each of the wireless transmitter 120 and the wireless receiver 200 mayadopt an ASIC chip which only has normal receiving and transmittingfunctions, thus further reducing the cost. Certainly, each of thewireless transmitter 120 and the wireless receiver 200 may adopt acommercially available chip, for example, a wireless sensor networkchip, a Zigbee chip, a 315M or 433M wireless transceiver module, or a27/40/62 MHz FM/FSK wireless receiving and transmitting chip.

FIG. 2 is a block diagram of a home lighting control according to anembodiment of the present disclosure. In one embodiment, as shown inFIG. 2, the controlled component 400 is a lighting device, and thecontroller 300 is a relay dimmer switch, a coupler or a thyristor forcontrolling the lighting device 400 to turn on or off. In this way,because wireless connection is adopted, a switch for controlling thelighting device may be disposed in any position of a room, thusfacilitating the use of the user.

In one embodiment, for example, in an application scenario, there may bea plurality of wireless transmitters 120 and a plurality of wirelessreceivers 200 working at frequencies matching each other, and theplurality of wireless transmitters 120 match the plurality of wirelessreceivers 200 according to identity codes set in the firstidentification cards 130 and the second identification cards 210. Maybeone wireless switch 100 matches a plurality of wireless receivers 200according to identity codes set in the first identification card 130 andthe second identification cards 210, maybe one wireless receiver 200 maymatch a plurality of wireless switches 100 according to identity codesset in the first identification cards 130 and the second identificationcard 210, maybe a combination thereof is adopted.

As shown in FIG. 2, the switch assembly according to an embodiment ofthe present disclosure is described by taking home lighting as anexample. Certainly, the switch assembly according to an embodiment ofthe present disclosure may also be used for controlling a home applianceor an industrial control apparatus needing simple control. For example,for a television, infrared control is adopted by a conventional remotecontroller, so that not only the cost is high, but also the remotecontroller must face toward the television to control the television.With the switch assembly according to an embodiment of the presentdisclosure, not only may the cost be reduced, but also the user maycontrol the television in any position of a room. In this embodiment, acontrol instruction from the wireless transmitter 120 may not onlycomprise a switching instruction, but also comprise other instructionssuch as a channel adjustment instruction or a volume adjustmentinstruction.

In one embodiment, the wireless transmitter 120 may be powered by abattery, so that the wireless switch may be disposed in any position.Certainly, the wireless transmitter 120 may be powered by a supply lineof commercial power. Similarly, the wireless receiver 200 may be poweredby a battery or a supply line of commercial power.

With the switch assembly according to an embodiment of the presentdisclosure, remote control may be achieved by a wireless receiving andtransmitting module with low power consumption, and consequently complexcontrol wiring is not required, thus reducing a complexity of wiringgreatly, saving wires and cables, and saving the cost. The switchassembly according to an embodiment of the present disclosure may notonly apply to home lighting systems and electric apparatus, but alsoapply to industrial apparatuses only needing simple control. Comparedwith a conventional infrared structure or conventional radiofrequencystructures, the wireless switch and the wireless receiver haveadvantages. Each of the wireless transmitter and the wireless receivermay be an ASIC chip which only has normal receiving and transmittingfunctions, thus further reducing the cost. Next, the identificationcards are used to match the wireless switch and the wireless receiver,so that the wireless switch and the wireless receiver may bemass-produced without a matching problem. In a small space, ever if aplurality of the wireless switches and a plurality of the wirelessreceivers work at frequencies same with each other, confusion may notoccur, thus extending an application range of the switch assemblyaccording to an embodiment of the present disclosure. In addition, thewireless switches and the wireless receivers which are mass-produced mayfurther reduce the cost, thus having very good market outlook.

With the switch assembly according to an embodiment of the presentdisclosure, an IC memory card slot or a chip socket is innovativelydisposed on a transmitting and receiving devices respectively so thatthe user may change identity codes at any time according torequirements. For example, when selling, a merchant may provide aplurality of pairs of IC memory cards or memory chips to a customer, anda unique identity code is set in each pair of IC memory cards or memorychips, so that the user may mount corresponding IC memory cards ormemory chips on the transmitting and receiving devices according torequirements. Alternatively, for a large-scale application scenario, forexample, electrical wiring of a building, the user may select a fieldprogrammable IC memory card or memory chip. After a correspondingidentity code is written in an IC memory card or a memory chip, the ICmemory card or the memory chip is mounted into an IC memory card slot ora chip socket, which is very convenient.

FIG. 3 is a block diagram of a wireless switch for a strong electricitycomponent according to an embodiment of the present disclosure. Thewireless switch 100 further comprises an IC memory card slot or a chipsocket 140. The first identification card 130 may be an IC memory cardor a memory chip. The control switch receives a touch of a user forproducing a control signal. One or more identity codes are set in the ICmemory card or the memory chip 130, and the wireless switch 100communicates with one or more wireless receivers 200 controlling astrong electricity component and sends the control signal to the one ormore wireless receivers 200 when the second identification card 210 andthe first identification card 130 have at least one same identity code.After the control switch 110 is touched, the wireless transmitter 120sends a control instruction according to one or more identity codes setin the IC memory card or the memory chip 130. In this embodiment, theidentity codes and the control instruction may be sent together, and thecontrol signal comprises the identity codes and the control instruction.In other embodiments, after modulated using the identity codes, thecontrol instruction may be sent. The IC memory card may be a SIM card.

In one embodiment, the IC memory card or the memory chip 130 may befield programmable, so that the user may write an identity code in theIC memory card or the memory chip 130 according to onsite requirements.Therefore, the user may use the IC memory card or the memory chip 130conveniently.

In one embodiment, the control switch 110 may comprise a touch switch,for example, a conventional control switch for an electric lamp. In oneembodiment, because the switch assembly according to an embodiment ofthe present disclosure is different from a conventional control switchfor an electric lamp and may send a control instruction, the switchassembly according to an embodiment of the present disclosure may havevarious modes, for example, adding an “ON” button and an “OFF” button ona switch panel or adding a button for controlling a luminance of anelectric lamp and a timing button, thus enhancing use and controlefficiencies.

In one embodiment, the wireless switch 100 may be powered by aphotovoltaic component and a rechargeable battery or a super capacitor.The photovoltaic component is set on a panel of the wireless switch 100.The rechargeable battery or a super capacitor is connected with thephotovoltaic component for storing an electric energy generated by thephotovoltaic component and supplying power to the wireless switch 100.In one embodiment, the photovoltaic component may be an amorphoussilicon solar cell or an organic dye solar cell.

In one embodiment, there are a plurality of wireless switches 100, andeach wireless switch 100 corresponds to a certain number of identitycodes.

In some embodiments, there are a plurality of control modes, forexample, a one-to-one control mode, a one-to-multiple control mode, amultiple-to-one control mode, or even a multiple-to-multiple controlmode. For example, the one-to-multiple control mode is as follows: thereare one wireless switch 100 and a plurality of wireless receivers 200,in which at least one identity code set in the second identificationcards 210 in the plurality of wireless receivers 200 matches theidentity code set in the first identification card 130 in the wirelessswitch 100; the multiple-to-one control mode is as follows: there are aplurality of wireless switches 100 and one wireless receiver 200, inwhich at least one identity code set in the first identification cards130 in the plurality of wireless switches 100 matches the identity codeset in the second identification card 210 in the wireless receiver 200;and the multiple-to-multiple control mode is as follows: there are aplurality of wireless switches 100 and a plurality of wireless receivers200, in which a plurality of identity codes set in the firstidentification cards 130 in the plurality of wireless switches 100 matcha plurality of identity codes set in the second identification cards 210in the plurality of wireless receivers 200.

For example, when the user moves into a door and switches on onewireless switch, the wireless switch may control all lamps in everyroom, that is, identity codes corresponding to all the lamps in everyroom are set in the wireless switch, so that the lamp in each room maybe turned on by the wireless switch at the door. When the user movesinto a living room and wants to turn off lamps in a passage, a kitchen,etc., one wireless switch is also disposed in the living room and maycomprise a plurality of components each corresponding to a certainnumber of identity codes. For example, the wireless switch in the livingroom comprises two switch components, an identity code corresponding toa lamp in the living room is set in one switch component, and anidentity code corresponding to lamps in the passage, the kitchen, etc.is set in the other switch component, so that the user may not only turnoff the lamp in the living room by the wireless switch, but also turnoff the lamp in the passage or the kitchen. In this example, when theuser moves into a bedroom and prepares for sleep, all the lamps may beturned off by a wireless switch in the bedroom. Certainly, the wirelessswitch in the bedroom may also comprise a plurality of switch componentseach corresponding to a corresponding identity code.

In the above example, the description of the switch assembly accordingto an embodiment of the present disclosure by taking a house as anexample is for the purpose of illustrating the present disclosure moreclearly, however, the switch assembly according to an embodiment of thepresent disclosure may also apply to a more complex scenario, forexample, building lighting control.

FIG. 7 is a block diagram of a relay forwarding control system for astrong electricity component according to an embodiment of the presentdisclosure. The relay forwarding control system may not only apply to alighting system such as a street lamp or a building lighting system, butalso apply to other control systems for a strong electricity component.The relay forwarding control system comprises a first wireless controldevice 7100 and a plurality of wireless relay control devices 7200. Theplurality of wireless relay control devices 7200 may communicate witheach other in a hop-by-hop manner, in a cellular manner, or in othermanners, and transfer a control signal.

The first wireless control device 7100 controls a first controlledstrong electricity component, has a first receiving identity code and afirst transmitting identity code, and is configured to control the firstcontrolled strong electricity component according to a controlinstruction after a matched control instruction is received according tothe first receiving identity code and to forward the control instructionto a next hop wireless relay control device 7200 according to the firsttransmitting identity code. Each wireless relay control device 7200controls one controlled strong electricity component, for example, astreet lamp, and has a corresponding receiving identity code and acorresponding transmitting identity code. These receiving identity codesand these transmitting identity codes may be identical with or differentfrom each other, which may be determined according to particularapplication scenarios. However, because a pluggable IC memory card or apluggable memory chip is used, the user may conveniently use thereceiving identity codes and transmitting identity codes in a particularapplication.

In some embodiments, the receiving identity code of each wireless relaycontrol device 7200 matches the transmitting identity code of a previoushop wireless control device (which may be the first wireless controldevice 7100 or a previous hop wireless relay control device 7200), thetransmitting identity code of the each wireless relay control device7200 matches the receiving identity code of a next hop wireless controldevice, and each wireless relay control device 7200 is configured tocontrol a corresponding controlled strong electricity componentaccording to a control signal, for example, control a street lamp toturn on or off, after the control signal matching the receiving identitycode of each wireless relay control device 7200 is received. Inaddition, each wireless relay control device 7200 is further configuredto forward the control signal to a next hop wireless control deviceaccording to the transmitting identity code of each wireless relaycontrol device 7200, thus achieving relay transfer of the controlsignal.

In one embodiment, the next hop wireless control device is at apredetermined distance from the previous hop wireless control device,thus could be better applied in complex scenarios such as a multiplestreet lamp controlling. Therefore, one previous hop wireless controldevice may simultaneously control a plurality of next hop wirelesscontrol devices in the control range of the one previous hop wirelesscontrol device.

In order to avoid big load impact on a power grid, in one embodiment,each wireless relay control device 7200 forwards the control signal tothe next hop wireless control device according to the transmittingidentity code of each wireless relay control device 7200 after apredetermined time. In this way, by self delay of each wireless relaycontrol device 7200, the controlled strong electricity components maynot be turned on simultaneously, thus reducing the load impact on thegrid.

In one embodiment, the IC memory card or the memorychip is field programmable, so that the user may write the identitycodes as well as the channel assignment codes and independentidentifications mentioned below into them conveniently. In anotherembodiment, each wireless control device comprises a wireless receivingand transmitting chip which comprises a field programmable memory.Certainly, in other embodiments, a memory may also be integrated in achip, provided that field programmability is achieved.

In one embodiment, a receiving channel assignment code and/or atransmitting channel assignment code are also set in the IC memory card,the memory chip or the wireless receiving and transmitting chip, andeach wireless control device transmits and/or receives the controlsignal according to a channel assigned according to the receivingchannel assignment code and/or the transmitting channel assignment code,thus effectively avoiding channel interference among a plurality ofwireless control devices. Certainly, in some embodiments, because the ICmemory card or the memory chip is pluggable, receiving channelassignment codes and/or transmitting channel assignment codes may be setin some wireless control devices, but are not set in the other wirelesscontrol devices, for example, receiving channel assignment codes and/ortransmitting channel assignment codes may be set in wireless controldevices in a street with high density of lamps or where a lot ofwireless control devices are placed close to each other, thusfacilitating the configuration of the wireless control devices.

In order to prevent loss of the control signal or prevent the wirelesscontrol devices from being unable to be normally turned on sequentiallydue to interference, for example, the rest of wireless control deviceswill be unable to receive the control signal when one wireless controldevice receive a wrong identity code from a previous hop wirelesscontrol device, in one embodiment, a check code is also set in the ICmemory card, the memory chip or the wireless receiving and transmittingchip, each wireless control device determines whether the receivedtransmitting identity code of the previous hop wireless control deviceis correct, and if not, each wireless control device sends a failurefeedback to the previous hop wireless control device or requires theprevious hop wireless control device to retransmit, thus avoiding thefact that subsequent wireless control devices may malfunction becauseone wireless control device does not receive the control signal.

In one embodiment, each wireless control device further comprises astate detection module, for example, for detecting whether a currentflows through a controlled strong electricity component so as to detecta state, for example, an on or off state, of the controlled strongelectricity component. In one embodiment, each wireless control devicehas an independent identification set in an IC memory card or a memorychip. The state detection module is configured to detect a state of acontrolled strong electricity component and to feed a result and theindependent identification back to the previous hop wireless controldevice. After receiving the detection result and the independentidentification, the previous hop wireless control device continues tofeed the detection result and the independent identification back, untilthe detection result and the independent identification are fed back toa control center, thus determining which wireless control device isfailed in time and performing repairing and maintenance in time.

In one embodiment, a plurality of receiving identity codes and/or aplurality of transmitting identity codes may be set in each wirelesscontrol device, thus achieving one-to-multiple control, multiple-to-onecontrol, or even multiple-to-multiple control.

The relay forwarding control system according to an embodiment of thepresent disclosure has the following advantages.

(1) With the relay forwarding control system according to an embodimentof the present disclosure, the control instruction is transferred by theplurality of wireless relay control devices hop by hop, thus achieving along control range. Moreover, use of expensive GSM/CMDA modules may beavoided, thus reducing the cost greatly. Very good effect may beachieved especially in an environment such as a street lamp or abuilding lighting control system.

(2) With the relay forwarding control system according to an embodimentof the present disclosure, a very complex control network between alarge number of switches and apparatus may be conveniently configured bythe pluggable IC memory card or the pluggable memory chip. Moreover,because the IC memory card or the memory chip is pluggable, the wirelesscontrol devices may be produced in a uniform standard, thus reducing theproduction cost largely.

(3) With the relay forwarding control system according to an embodimentof the present disclosure, matching among wireless control devices inevery hop may be achieved by the use of the identity codes, and onlywhen the transmitting identity code of a previous hop wireless controldevice matches with the receiving identity code of this hop wirelesscontrol device, the controlled strong electricity component may becontrolled. In some embodiments, street lamps in a whole street or awhole region may be controlled using the relay forwarding control systemaccording to an embodiment of the present disclosure. In one embodiment,in order to avoid big load impact on a grid, each wireless relay controldevice forwards the control instruction to the next hop wireless controldevice after a predetermined time. Therefore, all the street lamps in awhole street may not be turned on simultaneously, thus reducing the bigload impact on the grid.

(4) With the relay forwarding control system according to an embodimentof the present disclosure, because a receiving wireless channelassignment code and/or a transmitting wireless channel assignment codeare also set in the IC memory card or the memory chip, each wirelesscontrol device may use an assigned receiving channel and/or an assignedtransmitting channel according to the channel assignment codes, thuseffectively avoiding channel interference among a plurality of wirelesscontrol devices. Furthermore, since flexible assignment may be achievedthrough present disclosure, the user may reduce the luminance of somelamps or turn off some lamps according to different periods of time orrequirements, thus saving energy greatly and conforming to green andenvironment-friendly ideas.

According to an embodiment of the present disclosure, a memory card isprovided, which may be used for matching wireless switches mainly byassociated identity codes. For example, respective identity codes areset in one wireless transmitting switch and one controlled component(for example, an electric lamp) having a wireless receiver, in whicheach identity code is stored in a memory chip, and the memory chips arepluggably inserted into the wireless transmitting switch and thewireless receiver respectively. Only when identity codes plugged in thewireless transmitting switch and the wireless receiver are associatedwith each other (for example, identical with each other), the wirelessreceiver may control the controlled component according to a controlinstruction transmitted by the wireless transmitting switch. However,because in a complex application scenario, relations among memory chipsin which identity codes are set are very complex, and even if the useris allowed to write identity codes in a field programmable manner, it isstill very inconvenient for the user. Therefore, according to anembodiment of the present disclosure, memory chips having associatedidentity codes are all disposed on one memory card body, thusfacilitating the use of the user. A plurality of memory chips, forexample, 4, 8 or 20 memory chips, may be disposed on one memory cardaccording to requirements.

FIG. 9 is a perspective view of a memory card for matching wirelessapparatuses or identifying a wireless apparatus according to anembodiment of the present disclosure. The memory card comprises a memorycard body 9100, in which a plurality of regions for containing aplurality of memory chips are disposed. The memory card furthercomprises a plurality of memory chips 9200, storing identity codes, andconnected with the memory card body 9100 through a plurality ofbreakable connection structures to fix the plurality of memory chips9200 in corresponding regions respectively, in which identity codesstored in at least part of the plurality of memory chips 9200 areassociated with each other. In this way, the memory chips 9200 may beconveniently taken down from the memory card body 9100 by the abovementioned breakable connection structures, thus facilitating the use ofthe user. Each memory chips may have a rectangular shape, and a smallpart of the memory card may be extended outward after the memory card isinserted into a corresponding apparatus, so that the memory chips may beplugged or unplugged conveniently. Certainly, the whole memory chips mayalso be inserted into a corresponding apparatus. For example, after twomemory chips 9200 having the same identity code are taken down from thememory card body 9100 by the user, a wireless switch and a controlledelectric apparatus may be matched after the two memory chips 9200 areinserted into the wireless switch and the controlled electric apparatus(for example, a lighting device) having a wireless receivercorresponding to the wireless switch respectively.

The above mentioned identity codes associated with each other indicatesthe control relationship between each wireless switch and each wirelessreceiver, for example, if there is a one-to-one control relationshipbetween each wireless switch and each wireless receiver, the identitycodes stored in two memory chips are the same; and if the abovementioned memory card comprises ten groups of memory chips with eachgroup has two memory chips, the same identity code is stored in the twomemory chips in each group, and different among groups, the memory cardhas 10 group of memory chips having different identity codes. In orderto ensure that the identity codes are not repeated, the length of eachidentity code may be 64 or 128 bits, and in the future, in order toachieve automated control network, each identity code may be managed asone IPv6 address.

If in a more complex application scenario, for example, in a street lampcontrolling or a building application, there may be a one-to-multiple ormultiple-to-multiple control relationship among the wireless switchesand the wireless receivers. For this case, assuming that the memory cardcomprises a memory chip 1, a memory chip 2, a memory chip 3 and a memorychip 4, the memory chip 1 may have an identity code identical with thatof the memory chip 3 and the memory chip 4 (certainly, the memory chip 3and the memory chip 4 may also comprise a plurality of identity codes),meanwhile, the memory chip 4 may have an identity code identical withthat of the memory chip 2 and the memory chip 3, thus achievingone-to-multiple control and multiple-to-multiple control respectively.Therefore, for this case, these memory chips may be all disposed on onememory card, so that the user may match the wireless switches and thewireless receivers onsite conveniently.

In addition, in a smart home application, a 128-bit identity code maycorrespond to an IP address in IPv6, an identity card is inserted intoeach controlled node, and the identity code and the node may be boundand matched by inserting the identity card in an intelligent terminal orinputting the identity code in the intelligent terminal, which is moresimple and more convenient compared with other matching method such as astudying mode, a searching mode, etc. Therefore, in one embodiment, onememory card may comprise a plurality of memory chips storing different128-bit identity codes, so that the user may set up a local area networkconveniently.

In a future smart home application, because there will be a plurality ofdifferent apparatuses, for example, an electric refrigerator, atelevision or an air conditioner, when the apparatuses are connected, itis first required that the household apparatuses are identified by anintelligent control terminal. For example, in some embodiments, thememory chips in the memory card may be divided into a main card and adaughter card (sub-card). As shown in FIG. 10, the memory card comprisesone main card 9300 and a plurality of daughter cards 9400. Identitycodes and necessary informations (for example, a channel assignment codeand an apparatus type code) corresponding to different types ofapparatus are stored in the daughter cards 9400, and correspondingidentity codes and apparatus type informations stored in all thedaughter cards 9400 are stored in the main card 9300. The channelassignment code is used for assigning a corresponding channel for anapparatus, and the apparatus type code may allow an apparatus where themain card 9300 is located to distinguish which type an apparatustransmitting an identity code is. For example, a refrigerator has acorresponding refrigerator type code, so that an intelligent controlterminal may send a control instruction to the refrigerator according tothe refrigerator type code.

After the user starts the intelligent control terminal, the intelligentcontrol terminal sends an acknowledgement signal comprising the identitycode of each apparatus to surrounding apparatuses according toinformation in the main card 9300, and detects which apparatus exists,that is, the acknowledgement signal is only sent to apparatuses withdaughter cards 9400 which are disposed on the same memory card as themain card 9300. If the acknowledgement signal is received by thesurrounding apparatuses, identity codes received by the surroundingapparatuses are compared with identity codes in the daughter cards 9400inserted into the apparatuses. When identity codes received by thesurrounding apparatuses conform to identity codes in the daughter cards9400 inserted into the apparatuses, the surrounding apparatuses sendinformation back to the intelligent control terminal to show that theyare online and may be controlled by the intelligent control terminal. Inthis way, the intelligent control terminal creates a new apparatus listinformation or updates an apparatus list information in its informationdatabase, and when necessary, the intelligent control terminal sends aninstruction information to a designated apparatus or receives aninstruction information from a designated apparatus for communication.According to an embodiment of the present disclosure, identificationamong different types of apparatuses may be performed using identitycodes in memory chips, and in order to facilitate the use of the user,associated memory chips are integrated in one memory card. In this way,identification among the intelligent control terminal and theapparatuses may be fully automatically performed without manualintervention, the fact that the intelligent control terminal controlsapparatuses of other families or apparatuses of one family are notcontrolled by the intelligent control terminal of the one family may notappear, and an apparatus manufacturer may not consider identificationproblem among his apparatus and other apparatuses at all. Identificationamong apparatuses may be completely determined by relationships amongdifferent identity codes stored in the memory card.

In one embodiment, the memory card body 9100 is a plastic component, andeach connection structure is a plastic connection bar. Certainly, othermaterials may be selected by those skilled in the art to form the memorycard body 9100.

In one embodiment, a channel assignment code is also stored in eachmemory chip 9200 for assigning a corresponding channel for an apparatusin which each memory chip 9200 is inserted. In this way, for a complexapplication scenario, different channels may be assigned for differentapparatuses, so that the apparatuses may not interfere with each other.

In one embodiment, apparatus type codes each corresponding to oneapparatus, for example, a refrigerator or a television, are also storedin each memory chip 9200, so that an intelligent control terminal mayassign corresponding control instructions conveniently.

In one embodiment, the memory chips 9200 in the memory card adopt thesame cipher key, and different memory cards have different cipher keys,so that one memory card and other memory cards bought by one family maynot control each other. In one embodiment, each memory chip 9200 adoptsa cryptographic algorithm and a cipher key which match each other.

In one embodiment, each memory chip 9200 may be a single line memory.Because the storage amount is small, a single line memory may be used.The data rate of the single line memory is low, however, it is highenough for application in the present disclosure, thus reducing themanufacturing cost of the memory chips largely.

In one embodiment, the length of each identity code is 8 bits to 2 kbits, preferably 64 bits, 128 bits or 256 bits. When the length of eachidentity code is 128 bits, the each identity code corresponds to an IPaddress in IPv6. Each identity code in the memory card is a codeconstituted by a group of digits. On one hand, these identity codes maybe pre-written or programmed in memory chips, for example, using a128-bit code randomly generated, and due to huge sample space of the128-bit random code, it is substantially ensured that the 128-bit randomcode may not be repeated. One random code is generated by a randomnumber generator, and written in a memory chips according torequirements. In this way, the random code may be generated randomly andassigned artificially, thus ensuring that the random code will not berepeated and meeting required relationships. On the other hand, acompiled random code may also be generated artificially, or may also berandomly generated in a certain designated digital section. For example,in an application of internet of things, a section of identity code isassigned for a certain type of apparatus. Before the memory cards leavesa factory, these informations have been already written, and the usermay only need to take a memory card home and insert the memory chipsinto an apparatus for matching. If in a complex application scenario, aprogrammable memory chip or disposable writable card may be used, andrequired identity codes are field programmable for matching.

In one embodiment, the memory card body 9100 further comprisesidentification information, for example, a bar code, so as todistinguish the memory cards. Meanwhile, a blank region in which wordsmay be printed may also be set on the memory card body 9100, so that theuser may mark identification information on the blank region. Forexample, when there are remaining chips after matching is completed,informations such as “bedroom lamp” or “kitchen lamp” may be marked foruse when sometime searching, replacement or changing.

In one embodiment, each memory chip 9200 may be a non-volatile memory,for example, a single line memory, a read-only memory, a programmablememory, Flash memory or EEPROM memory.

The memory card according to an embodiment of the present disclosure hasthe following advantages.

(1) With the memory card according to an embodiment of the presentdisclosure, by setting a plurality of associated memory chips in onememory card, the user may match the wireless control assemblyconveniently. Moreover, the memory chips are connected with the memorycard body through a plurality of breakable connection structuresrespectively, thus taking down the memory chips from the memory card issimple. Therefore, for the user, the memory card according to anembodiment of the present disclosure is convenient and easy-to-use; whena wireless switch and a wireless receiver are bought, only acorresponding memory card needs to be bought; for a particularconfiguration, identification and matching among wireless apparatusesmay be achieved by inserting memory chips having the same identitycodes; and in one memory card all the matching information (an identitycode in each memory chip) required by matching the transmitting andreceiving apparatuses which need to be matched are comprised. As aresult, the user may only need to pluggably mount memory chipscomprising identification and matching information to a correspondingapparatus according to requirements, matching is also very flexible, theuser may match a plurality of transmitters and a plurality of receiverstogether according to requirements by mounting memory chips with sameidentification codes in these apparatus respectively, and modificationor reconfiguration of the apparatus controlling relationships are veryconvenient and fast.

(2) The memory card according to an embodiment of the present disclosurealso has advantages of cost reduction for a manufacturer. With thememory card according to an embodiment of the present disclosure, anapparatus is separated from a matching information (i.e., an identitycode in a memory chip), thus wireless switches or receiving controlapparatuses may be produced standardly without the matching problems;and the required matching information may be achieved by the associatedidentity codes in the memory card, thus reducing the cost during theproduction and testing process. Moreover, for a current semiconductormemory production process, such a small-capacity non-volatile memory hasvery low cost, for example, even as low as a few cents per memory chips,and consequently the price of the whole memory card may be very low,which is economically feasible. With the memory card according to anembodiment of the present disclosure, during the production, themanufacturer may first standardly produce a memory card body, a blankmemory chip is disposed on the memory card body, and then the sameidentity codes are written into all the chips in the card according torequirements to finish the production.
